After a hot, dusty drive in our bouncing jeep, we finally arrived at what truly has to be one of the top natural wonders of the world. The only way to truly appreciate the immensity of this volcanic depression - Ngorongoro Crater - is to capture the view as a panorama. This is the largest unflooded and unbroken caldera in the world and has over 25,000 large animals within the Conservation Area, including 26 endangered black rhinos.
